To all whom it may concern:

Be it known that we, CARL G. SwEiLiUs and HANS T. R. HANiTz, respectively a citizen'of the United States and a subject of the Emperor of Germany, residing at New Haven, county of New Haven, State of Connecticut, have invented certain new and useful Improvements' in Repeating Firearms, of which ,the following is a full, clear, and exact description.

This invention relates to improvements in magazine repeating firearms.

The main objects of the invention-are to secure simplicity of construction and durability and effectiveness of action.

In the accompanying drawings, Figure 1 is a side elevation of our improved firearm with one side of the receiver removed to show the internal construction, the breech block being closed. Fig. 2 is a similar view, the breech block being opened. Fig. 3 is a horizontal-section on the linev 1/-3/ of Fig. 1. Fig. 4 is a horizontal sectionV oirthe plane of the same section line, with the breech block retracted. Fig. 5 is a tion on the plane of the line w, Fig. 1. Fig. 6 is a view ofthe inner side of that part of the side of the receiver which is removed from Figs. l and 2. Figs. 7 8 and 9 are vertical sectional views, all similar, but showing the various parts of the action Fig. 10 is a perspective view of the inner side of one of the side plates showing theconstruction of the cam groove ther in. Fig.` 11 is a relatively enlarged view of the front end of the breech block and associated parts. Fig. 12 is a sectional detail view of part of the cartridge carrier. j

In the drawings we have 'shown our invention as applied to a take-down magawhich. the line of division the receiver, said receiver being divided longitudinal and vertically so that one side plate of the receiver will be carried rigidly barrel and the other by the stock.

Themagazine in this ranged underneath the barrel, and the breech mechanism is operated by a reciprocating action rod and handle. The firearm is also of the hammerlessf variety,

horizontal secinstance is a tube ar-V ranged It will be apparent that while we have shown the invention in connectiony with a gun possessing the aforesaid characteristics, in many respects said. invention' and the different features thereof may be embodied in guns possessing diiferent characteristics.

1 represents the stock.

2 represents the barrel.

3 represents the magazine.

'4 represents a handle slidable underneath l the barrel and! connected with, a reciprocating action rod 5 which projects back into the receiver.

6 represents one of the side plates'rigidly carried by the barrelu- 7 represents the opposite side plate rigidly carried Vby the stock.v

.8 represents an overhanging top plate rigidly carried by the side plate 6. Part of the upper edge of the side plate 7 is spaced away 4from the overhanging top plate 8 to form an opening through which the empty shells are ejected. 9 is the usual follower arranged to press the cartridges in the magazine rearwardly against a spring pressed cut-off 10, the latter being operated vin the, manner hereinafter described to release the cartridges,

vwhereupon they will be fed, one by one, into the receiver. 4The magazine may be filled with cartridges in the usual manner.

11 is a hammer mounted on a pivot stud 12 carried by the side plate 6.

13 is a hammer spring, in this instance in the form of a coil spring, one end of which is mounted in a recess in the hammer near the pivot stud, the other end being mounted in a recess in the lower part of the receiver. The expansion of spring forces the using a coil spring, the same readily conforms to the change in the angle of the hammer as it advances from the cocked position to the firing position.

14 is a trigger mounted on the pivot stud 15 in the lower part of the receiver, sai

lower part of Ithe receiver being rigidly attached to the-side plate 6 and being pro'- vided with atrigger guard 16.

17 is a reciprocating breech block arto slide to and fro within the receiver, there being a suitable guide-way l thisV hammer ahead, and byv 23 to its normal position in groove 18 formed in the side plate 6 to guarantee the accurate sliding movement of the breech block to and fro.

The 'breech block carries the usual spring pressed extractor hook 19, said hook being located adjacent the outer side of said breech block in a suitable groove. At the opposite side of said breech btlock is located the ejector 20 which has a peculiar movement best adapted to effectively eject the empty shells. As shown, the ejector is arranged in a groove and is movable to and fro, but the movement is in an oblique direction relatively to the line of travel of the breech block. This oblique movement is effected by means of an oblique cam groove 21 through which passes a pin 22.

23 is a retractor spring for the ejector 20. When the ejector is fully retracted, the pin 22 will stand at or near the front end of the groove 21. When the ejector is projected forwardly relatively tothe breech block the pin 22 will be located at or near the rear of the groove 2l, and as the ejector is operated, it will cause the same to partake of an oblique movement so as to follow substantially the rim ofthe cartridge as it turns in the extractor hook 19, thereby imparting to the cartridge a forceful, twisting, ejecting movement for a'sub'stantial period of time so as to guarantee a certain and effective expulsion of the discharged shell in the direc-- tion shown in Fig. 4. The outside of the ejector 20 has an offset shoulder which moves in avgroove 24 in the side plate 6. When the breech-block has nearly reached the end of its rearward excursion, this shoulder encounters the shoulder at the rear end of the groove 24 and is checked from further rearward movement, hence, as the breech-block continues to move rearwardl there isa relatively forward movement' of the ejector which results in expelling the discharged shell. When the breech block is advanced, the ejector returns under the action of spring which vits nose stands in the proper position opposite the yhooked end of the extractor 18 to engage another cartridge, after the manner shown in Figs. 7 and 9, and hold it While it is being fed into the chamber of the barrel, discharged and removed therefrom.

25 is a spring retracted firing pin which is i arrange 1n the breech block, the rear end being exposed to the hammer 11 in the usual manner, the forward end being arranged to lengage with part of the cartridge which it is desired to strike when the latter is to be discharged,

26 represents the locking being mounted in the breech block to move up and down, the upper end of the locking bolt being arranged to engage a locking shoulder or abutment 27 on the under side bolt, the same at its front end lower part of the locking bolt is provided with a lateral offset 28 which has its front and rear bearin surfaces preferably beveled in a forward and downward direction whereby the same maybe engaged by the rear end of the action rod which is provided with a notch forming a stepped incline or cam, as best seen in Fig. I2, so that the final forward movement of the action rod 5 will actuate the locking bolt to throw it up into the lock-y ing position shown in Figs. 1 andA 7 wherein the loc-kin r bolt stands with the lateral offset 28 restlng upon the ledge 29 so that the bolt will .be positively held in the ele-v vated, or breech-block locking, position. When the action rod 5 is retracted from this position, the first slight movement will be free, and then the cam incline 30 will-engage the offset 28 and will first pull down the locking bolt, disengaging it from the abutment shoulder 27 and thus unlocking the breechblock. Further rearward movement of the action rod 5 will force the breech-block and the locking bolt bodily back, the rearward movement of the breech-block cocking the hammer l1.

The cartridge carrier is indicated at 31 and comprises a block which moves up and down in a guide-way in the forward part of the breech-block, which latter has a suitable depending forward portion in which said guide-way is formed. The cartridge carrier has a forwardly projecting upwardly hooked nose 32 having an inclined upper as well as an inclined lower surface. The upper incline is designed to receive the rearmost cartridge in the magazine to guide 1t rearwardly into the position shown in Fig. 7. The lower incline is designed to engage the cut-ofi' 10 when the breech block is fully advanced to depress said cut-off and release the rearmost cartridge to permit it to move into position on top of the hooked nose 32 of the carrier. In the front end of the breech block there is an ascending guide groove undercut at 33-33, Fig. 11, to receive the flange of the cartridge to properly hold it as it is being guided up to position in the rear of the barrel where it is engaged by the ejector and extractor. The moveis effected by means of a is cam is formed by a upper path of arched design and a lower return path, both paths meeting at the ends. The forward path is deepest at the rear endand shallows up toward the forward end until it reaches a drop-off shoulder 36 adjacent the deep end of the return path. The return path shallows up at its rear end until it reaches a drop-off1 shoulder 38 adjacent the'deep end of the forward upper path.

34 is a spring stud in the side of the carcam, Fig. 10. Th groove having an e7 (Fig. 1o).

carrier then descends rier projecting into the cani groove. As the action mechanism is movedfrom the position shown in Fig. 7 to that shown in Fig. 8, the spring-stud 3 4 rides along in the lower path and is slightly elevated by the incline As this lower'path shallows' up, the spring stud 34 is repressed until finally it drops over the shoulder 38 into the deep end of the forward upper path, said drop-off occurring when the partsassume approximately the positionshown in 8. The advance movement of the action mechanism causes the stud to ride up the incline 35 following the course of the upperarched path of the cam groove, which causes the carrier to quickly ascendy to the osition shown in Fig. V9, carrying the cartridge up through the guide roove in the front of the breech block and into position where it is engaged by the extractor and ejector. v The by reason of the stud following the descending part of the upper path until the action mechanism reaches a proximately its forward positionwhere t e stud 34 drops over the drop-off shoulder 36 into the deep end of the `ower path. On this last part of the forward movement, the said cartridge is fed into the bore ofthe barrel and the locking bolt is actuated to lock the breech so that the parts will assume the position shown in Fig. 7. The stud isiniiuenced by a spring 34a. The drop-off shoulders 36'and 38 form abutments which'pre vent the estud from following an other course in the cam groove than t at described; As the stud 34 Vmoves around the course of the cam groove, thecarrier will be alternately elevated and depressed, the movement thereof being-timed by the shape ofthe cam groove so'as to coperate prop.- erly with the other parts ofthe laction mechanism.

It is obvious that for safetys sake some means must be provided to prevent the acci'- E breech block is locked up dental discharge ofthe firearm until the To that end we provide a simple and effective safety locking means, automat-ic'iii action. This safety locking means comprises a safety bar 39 which is 'carried in a' recess'uin the inner side of the side late 7 (see Fig. 6). This recess is so shape and the bar-is so arranged i therein that it partakes of both aflongitudinal and a v tilting f movement.

I' thereof but-nearerithe rear endl, The lup-` vwardl'y pro'ecting nose 42 is designed to coact with t e act1on-rod 5. The sa ety bar coacts with the hammer to prevent thel same from descending from its cocked position until the gun is fully locked, even though in the meantime the trigger Vis pulled. It also coacts withthe action bar so that the handle 4 cannot be ulled rearwardly to unlock the .when t 'e hammer is cocked and after the breech block is locked up with av cartridge in the barrel. i' fully locked, the pulling When the gun 1s pf the trigger will release the hammer to discharge t the hammer will (by means e shell and this movement of immediatel after the shell is discharged. On the hu of the, safety e of the hammer are two 4abutment shoulders.

One of the shoulders 45 is at theirear of the *i pivot point ofthe hammer and faces upwardly. The other shoulder 46 is forward of the pivot point of the hammer and faces downwardly. These shoulders 45446 coact with the lateral noses 43-44 on the safety I' bar. When the parts stand as shown'in Fig. 1, it will be observed that the nose 43 on the safety bar stands above shoulder 45 on the hammer. tion, into a notch 47 in the under side of the acl tion rod 5. .In this position the gun is fully locked, for aswill be seen .from reference to Fig. 6, the lower'side of the safety bar is provided with a depending nose 101 which engagesagainst a fixed shoulder 102 formed byrecessing the side plate 7 to for the nose 101 to enter an shoulder 102 when the safety bar stands in the position shown in Fig. 6., If the trigger 14 is now pulled, the hammer is released and In this osirovide room Y engage the the upwardly facing lthe nose 42 on the safety bar projects springs forwardly,'s'triking against the ir-- ing pin to discharge the shell in the bore of. t When thehammer has about descended and hit thefiring pin, the upwardly facing shoulder 45 0n the hammer hub engages the-nose 43 on the safety bar andtilts the bar 0n its fulcrum 41 so as to withdraw1 the nose 42 from the notch 47 in the action rod 5,7simultaneously disengaging nose 101 from the shoulder 102.` This releases the action rod so that it maybe pulled rearwardly to unlock manner previously described andgto shift the same rearwardly to the .position indicated in Fig; 2, thereby causing. the empty shell lto be withdrawn and ejected and simultanethe breech bloc-k in the ously cooking the hammer. This movement,

of the breech block swings the'hammer somewhat back of its cocked position so that the.

of the laterally safety har. On rearward movement of 1Lllncsijecting. nose 44 on the .the breech block, the depending forward part thereof strikes the forward side of the nose 44- and pushes it (and the safety bar) rearwardly, causing saidnose 44 to sllde under the downwardly facin shoulder 46 on the lhub of the hammer so t at the parts will'assume the position indicated in Fig. 2. This rearward movement of the breech block and its associated parts will withdrawpa fresh cartridge from the magazine ready to transfer it to its position between the ejector and extractor as previously described. The forward movement of the action rod handle 4 from the position shown in Fig. 2 will carry the breech block ahead, the carrier simultaneously lifting the cart-ridge to the. aforesaid position so that said cartridge will be inserted into the bore of the barrel. Just before the action rod reaches the limitof its forward excursion, the nose 42 at the forward end of the safety bar will be projected into the notch 47 on the under side of the action rod so that the linal forward movement of the action rod will pull the safety bar bodily with it from the position indicated in Fig.v 2 to that indicated in Fig. 1, shifting the nose 44 from the position shown in Fig. 2 t0 that shown in Fig. 1, thus re- Ileasing the hammer and allowing it to partially dropto the position where it is supported by the trigger, and simultaneously moving the nose 43 to the position where, when the hammer descends, it will be enga ged by the shoulder on the hub of the hammer to release the safety bar from the action rod when the gun is tired, as previously explained.

From the foregoing it will be seen that during the forward movement of the action rod, the cocked hammer cannot possibly descend until the action rod has reached the limit 0f its forward movement wherein the breech block is safely locked. It will also be seen that so long as the breech block is safely locked and the hammer is cocked, theA ,action rod cannot be pulledk rearwardly by the hand of the user of the gun whilehe is taking aim and ispulling rearwardly to hold the gun properly seated'against his shoulder. When, however, the hammer has fully descended and the cartridge discharged, the action rod will be released so that the pump handle 4 may be pulled rearwardly to discharge the empty s ell, cock the hammer and reload the gun for 4another shot.

48 is a finger piece which is exposed at the side of the gun and is connected through a slot in the side plate 7 with the safety bar so that it is possible to manuall manipulate the safety bar to release the actlon rod withoutpullin the trigger and dropping the hammer w ereb any cartridge in the barrel may be reatly removed Without being discharged.

We also provide a safet latch for the trigger which comprises a olt 49 slidable in the frame of the receiver directly in advance of the trigger, the nose of said bolt being arranged to project into a notch 50 in the hub of the trigger when the hammer is cocked. This bolt 49 is providedwith a finger piece 51 which is ex osed adjacent to the trigger guard and W ich may be engaged b the finger so that said bolt' may be slid orwardly to the position shown in Fig. 2 where the trigger is free, or rearwardly to the positionshown in Fig. 1 where the trigger is locked.

As already stated, we have shown the invention as applied to a take-down firearm in which the barrel is detachable from the receiver, the parts being suitably interlocked. In this case the side plate 7 is provided w-ith a locking shoulder 52 (Fig. 6) which engages with a lookin shoulder 53 formed by undercutting the slde of the receiver, as shown in Figs. l and 2. This interlocks the parts at the forward part of the receiver, while a thumb bolt 54 secures said parts together at the rear part of the receiver.

It will be observed that the firing pin 25 passes through a vertical slot in the locking bolt 26, thereby preventing the accidental disengagement or loss of the latter from the breech block when the gun is taken apart. The finger piece 5l of the trigger safety bolt is adapted to be held frictionally in place in either position .by means of an overlying friction spring, indicated at 52.

The operation of the ejector is effected not only by means of the slot 21 and pin 22, but also by means of the tension of the thin tail which extends to the rear, it having been found in practice that the ejector is more effective by reason of the thinning down of the rear tail end than where the construction is such as to prevent tension from this part of the ejector;
